This species is very similar to Antaeotricha lindseyi. Possibly the 

 two are conspecific, but until series of A. lindseyi can be obtained and 

 the variation studied, I prefer to recognize them as distinct species. 

 They may be distinguised by differences in the shapes of the aedeagus 

 and of one of the anellar lobes. Significant differences in the female 

 genitaUa have not been found.
